About This Invention
Ground penetrating radar (GPR) is used to locate pipes, rebar, utility lines, and other objects hidden below a surface — but knowing an object is there is only half the problem; knowing precisely where it is matters just as much. This patent protects a system that improves the positional accuracy of a GPR unit by detecting objects at two or more points along their length and comparing the collected radar data against modeled, previously recorded, or predicted data. Our firm has obtained a family of GPR-related patents in this field for the same client.
Abstract
A system for obtaining improved position accuracy with ground penetrating radar includes a position locating device capable of detecting objects, such as substrate objects, at at least two points along an extent thereof. Methods for its use include collecting, modeling, and comparing detected radar data with other detected radar data and/or previously input data and/or assumed and/or predicted data.
Representative Claim
Claim 1 of 20 — the complete claim set is available in the full patent record.
1. A position locating device comprising:
a ground penetrating radar transceiver; and
a location determining system;
wherein said device is configured such that a first detection, by way of said ground penetrating radar transceiver, of a first subsurface object at, at least, two different points, said two different points extending in a direction other than a path of travel of said position locating device during said first detection, is used to correct a pose of said position locating device relative to said first subsurface object based on an assumed or determined linear extent of said subsurface object.
